How can I install Jekyll on Ubuntu 10.04 Server?

问题

The definitive guide to installing Jekyll seems to be https://github.com/jekyll/jekyll where it says:

gem install jekyll

I am getting an

ERROR:  could not find gem jekyll locally or in a repository

regardless of whether I run that command as superuser or not.
gem env Returns the following:

RubyGems Environment:
  - RUBYGEMS VERSION: 1.2.0
  - RUBY VERSION: 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]
  - INSTALLATION DIRECTORY: /var/lib/gems/1.8
  - RUBY EXECUTABLE: /usr/bin/ruby1.8
  - EXECUTABLE DIRECTORY: /var/lib/gems/1.8/bin

  - REMOTE SOURCES:

     - http://gems.rubyforge.org/

I have also tried specifying github as the source with no luck. What else should I be trying?

回答1:

You are using a very outdated version of RubyGems.

First, update the sources:

$ gem sources --clear-all
$ gem sources --add http://rubygems.org
$ gem sources --add http://gems.github.com

Then try to install it.

You should also login as a superuser and update the RubyGems version. The current release is 1.3.7.
